Abstract

A cable 302 has 8 fibres 304 are encapsulated by a UV curable layer 306 having a diameter of approximately 1010 microns, and 16 outer fibres 316 arranged in a circular formation around the inner fibres 304. The optical fibres 304 are held in position by means of the UV curable layer 306 so that the UV curable material of the layer 306 does not penetrate into the gaps between the optical fibres 304 and the outermost optical fibres 304 are restrained by the layer from moving axially. It is found that such an arrangement provides surprisingly favourable bending properties, making the cable particularly suitable for installation in a tube by means of blowing.
